Double Glazed Windows Repairs

There are a variety of reasons your double-glazed windows could require repair including condensation between panes to dropping or sagging frames. Fortunately, a majority of problems can be addressed.

If your window or door is difficult to open, try oiling the mechanism, hinges and handles. This is a quick and affordable fix.

Broken Panes

When a window is damaged it loses its insulation and can cause a draft. If the muntins that separate the glass panes also broken, moisture can get in between them and cause condensation, mould or mildew. This will make your home less efficient in energy use. It is best to have a professional repair the damaged window in order to get the best seal and energy efficiency.

First, you'll need to remove the broken glass. Start by placing an inexpensive glass cutter in a hardware store under the broken pane. Before you begin, make sure to lubricate the cutter of this tool using an oil that is light. This will help prevent the glass from breaking too easily. The ball-shaped end of the tool can be used to loosen the pieces. They should come off quite quickly.

Scrape any old glazing compound off the frame's recess after the glass is removed. This will reveal the glazier's clips and pins that keep the glass in the frame. If there's evidence of corrosion, the clips must be replaced with new ones. If the window is made of wood, the glazier's points can be re-used if they're still intact.

The next step is to prepare the surface of the frame for reglazing. Utilizing a caulking gun apply a continuous strip of compound around the inner edge of the recess. Use a high-quality putty such as glazier's compounds that is contained in a cartridge or conventional compound that comes in a tin. It should dry before installing the glass. If the frame has metal clippings, they should be replaced as well. Reinstall the divider muntins.

Condensation

Condensation is one of the most common issues that double-glazed windows can experience particularly in wintertime. It is typically caused by excessive moisture levels in your home. Warm air is absorbed by cold glass and condenses to water droplets. These then collect in the corners and frame of the window. This can be prevented by opening windows more frequently and enhancing ventilation with extractor fans, and using dehumidifiers to reduce moisture levels. If condensation is still an issue, it's crucial to call in an expert to get to the bottom of the issue and repair or replace your windows if needed.

Condensation on a double-glazed glass window is a sign the seal has failed. The seals that are applied at the factory can wear out over time and allow cool air to pass between the panes. This can lead to fogging of the window and eventually mold growth if not dealt with promptly enough.

Hairdryers can be used to get rid of excess moisture. However, this is just an interim solution and should be used as the last option. If you let the condensation sit for too long, it could lead to mould or dampness within your home. This issue should be handled by an expert.

Professionals can seal your double-glazed window to provide a longer-lasting solution. They'll remove the damaged glass pane, clean the gap and pipe hot air into the area to eliminate any moisture. In this process, they'll look for signs of damage, mildew or mould growth and apply a draught-proofing treatment to ensure that your windows are completely operational and energy efficient again.

Draughts

As time goes by the rubber seals around the edges of your insulated glass can be damaged and create a draught in space between the two panes. This is usually a minor problem that can be fixed by re-installing the gaskets and this will result in a solid and airtight seal once again. This will keep warm air inside your home, and colder air outside. You'll reduce your energy bills.

Misted double glazing indicates that the seals of your sealed unit (sometimes called a DGU) have blown. The unit is composed of two glass panes filled with argon separated by a spacer, creating an airtight window. If the seal has blown it allows water vapour to get into your space through the gap, causing condensation between the panes that can't be removed.

Fortunately it is a simple problem to fix and windows can be replaced quickly by experts with the right tools and know how to do it correctly. The expert will employ an instrument that is designed to push into the new seals. This is generally faster than doing it manually. The tools have a pointed tip that can be used to push seals into corners.

In certain situations an expert may be able to 'reseal your windows' by drilling a small hole in the window and adding a special desiccant material or putty. This could be more cost-effective than replacements, and will provide a reliable protection against draughts for your double-glazed windows.

Faulty Hinges

Many people have experienced misted double glazing. It may be caused by a broken seal or crack in the glass or an issue with the mechanism or frame. It is possible to fix this problem. Normally, this involves creating a new seal between two panes of glass. The new seal will stop condensation, draughts, and leaks from occurring.

If you spot any problems, you should contact the company that sold you the windows. Make sure you do this in writing, and request them to confirm that they've received your notification. Having everything in written form will make it easier to resolve any disputes arise, because it will be easier to prove that you did complain.

A window repair expert may drill the gap between your windows in order to eliminate moisture and repaired form the seal. However, this is usually only a temporary fix and will not stop moisture from returning. Alternatively, it may be possible to replace the glass unit, which will ensure that it is watertight.

Remember that you should only attempt DIY fixes with the knowledge and skills you have are sufficient. Using super glue or another kind of DIY solution can cause more harm in the long term.

Broken Seals

Double glazed windows are held in place by seals on windows or gas. They are susceptible to damage due to many elements, including weather conditions, age and power washing. It is important to know the symptoms and the best way to fix them.

When a window seal fails, humid air can seep between the two panes of glass, creating fog. This is a common issue, and it can cause the window to appear visually distorted. Once the seal fails the argon or any other inert gas is lost from the glass, thereby decreasing its insulation properties.

A damaged window seal can be repaired by replacing it with a a new one by a professional glazier. This can be costly and might not be able to resolve the fog issue. Some companies offer defogging which involves placing a vacuum pump inside the frame of the window to eliminate moisture and make the glass clear. However this method isn't 100% reliable and cannot replace any inert gases, so the fog can come back.

If the IGU (insulated unit) is beyond repair, a glazier could replace it. This is typically the most cost-effective option and repaired can be a good choice when you're looking for a long-term solution. It is recommended to choose a company that offers a warranty for replacement windows to ensure that any issues are protected. You can be assured that your investment will yield the most effective results. You can also get rid of the issue by choosing the best quality product and following the care instructions that are provided by the manufacturer. This will prolong the life of the window and cut down the amount of repairs.
